HOSE-CLAM P.

SPECIFICATION forming part of Letters Patent No. 492,855, dated March'7, 1893.

Application filed December 9,

Syracuse, in the county of Onondaga,

ful Improvements in exact description.

My invention relates to hose clamps by which a hose is secured upon anipple or pipe.

My object is to construct a clamp from a single piece of wire, whichwill completely its free end will also it, and is provided with a loopor eye through which the fastening bolt or and which operates to tightensaid clamp by drawing said free ends toward forcing them apart or awayfrom each other, in either case tightening the size of the circle, windor coil around, embedding it into the hose; and in either constructionthe piece of wire itself to form an ob-. long loop of wire, and the endsof the wire itself, are secured together, the ends of said loop formingand being the loops or eyes encircle the hose, and partially encirclescrew is passed,

each other, or by clamp by reducing the is primarily bentupon throughwhich the bolt or screw isinserted.

My invention consists in forth in the claim hereunto annexed.

the several novel features of contruction and operation hereinafterdescribed and which arespecifically set It is constructed as follows,reference being had end of said screw and in which it rotates. Fig. 5,is a sectional elevation of Fig. 4, on line w, 00, therein. showing thesame construction as in Figs. 4 and 5, except that itis tightened'bydrawing the eyes toward each other.

A, is the clamp constructed by first bending a wire to form loops oreyes 1 and -3 at the ends, and securing the ends of the wire together toform the intermediate clamp body -2-, composed of two strands, the samebeing divergin so wider than the other. Ihis looped clamp body is thenbent centrally to form a circle, the end carrying the loop or eye 1being passed through said crossed, or the eye -1- again tucked throughthe body adjacent to the eye -3 so as to bring said eyes in oppositerelations to those shown inFigs. 1 and 2, In either case, the eyesthemselves are bent so as to stand at an angle as shown. InFigs. 1 and 2said eyes are adapted to receive an ordinary bolt and nut; but in Figs.4' and 5 the eye -3 consists of a coil formed transverse to the body ofthe clamp, coiled tightly, so that the convolutions form, in themselves,the threads which engage with the coarsely threaded screw.

In Figs. 1, 2 and 6, the clamp is tightened by drawing the eyes -1- and-3 inwardly or toward each other; and in Figs. 4 and 5 it is tightenedby forcing them apart, or away from each other. In either case, thecomplete circle first made, by bending the body, creates two strands ofwire around the hose, and the remainder of the bending creates two otherstrands extending nearly around it in Figs. 1, 2 and 6; and-clear aroundit in Figs. 4 and 5, so that in the latterthere are four strands aroundit all of which are tightened simultaneously.

What I claim as my invention, and desire to secure by Letters Patent,is-

A hose clamp, comprising a wire, form a looped body, ends formed bycoiling bent to and eyes at its extreme the wire, the sides of said bodydiverging from the eyes toward body,and the free ends of the loop arebrought up either contiguous to each other as shown in Figs. 1 and2,0rare Fig. 6,is a side elevation that one end is each other, andadapted to be wrapped clear In witness whereof I have hereunto set myaround the hose, one end being passed through hand this 12th day ofNovember, 1891. the body in wrapping it about the hose, said eyes beingbent outward, substantially par- WEIDAWf In presence of HOWARD P.DIMsoN, HERBERT A.

5 ailel to each other, and a bolt inserted through said eyes and meansfor securing it, as set forth.
